This 4-Port Portable USB 3.0 Hub with Built-in Cable turns a single USB 3.0 port into four, letting you connect more of your devices to your computer.

The hub features a built-in, 25 cm (10 in) cable that is longer than what most traditional hubs offer. The extended-length cable gives you the flexibility to place the hub and your devices exactly where you want them, and it ensures the hub can connect to your laptop or tablet regardless of where the laptop’s USB 3.0 port is located.

Expand the connectivity of your laptop when you travel

With an integrated cable you have more flexibility to place the hub on your desk as desired. Plus, the hub is USB-powered for easy transport when you travel.

Upright port-configuration saves desk space

This USB hub offers a block-style design with ports placed across the top surface of the hub. With upright port access your connected devices (for example, flash drives and mouse and keyboard wireless receivers) take up less desk space.

Alternatively, you can lay the hub on its side for easy cable connections to devices like external hard drivers or printers.

Designed for easy use

With its compact design, you can easily position the USB 3.0 (also known as USB 3.1 Gen 1) hub on your desk or workspace to make your USB devices more accessible. There’s also ample space between the USB 3.0 ports, so it’s easy to plug and unplug the devices you use the most.

The USB 3.0 hub is natively supported in virtually all operating systems, which makes for an easy setup with no driver installation required. And because it’s backward compatible, you can connect both new and legacy USB devices (for example USB 2.0 peripherals).

The ST4300PBU3 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Applications

Flexible hub placement options with an extended-length cable, so you can connect a wide variety of peripherals at home or in the office

Ideal for Laptop and Ultrabook™ users with limited USB 3.0 ports

Make hard to access USB ports more accessible, by positioning the hub anywhere the cable will reach

Frequently Asked Questions

Before You Buy

It is possible to use some USB hubs without a power supply, however, doing so may prevent the USB hub or certain high-power USB peripherals from operating. It is always recommended to use an included power supply with a USB hub when possible.

When a power adapter is not used on a hub that comes with a power adapter, power is drawn from the USB port on the computer and then divided between the ports on the hub. This reduces the power delivery to individual ports and high-powered USB peripherals, such as external hard drives, may not start.

On USB hubs that can use a power adapter, more power can be supplied to USB ports than what is possible with a single USB port.

If your USB peripherals require power adapters, they probably do not require power from the USB port and can be used on a USB hub without a power adapter. With USB peripherals that use power adapters, the USB ports on the hub are only used for data transfer and do not draw power from the hub.

USB peripherals that require low power (for example, keyboards and mice) can be used on hubs without a power adapter, in conjunction with other low-power USB peripherals. In this case, power is drawn from the computer's USB port, as described above.

Troubleshooting

When you troubleshoot issues with a USB hub, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

USB A-to-B cable

Computer USB port

USB peripheral(s)

To test your setup components, try the following:

Use the USB cable and USB peripheral(s) in another setup to see if the problem is with the components or the setup.

Use a different USB cable, USB port, and USB peripheral in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

Test each cable individually.

Use short cables when you are testing.

When you test the hub, make sure that you do the following:

If a power adapter is included, provide power to the USB hub.

Attach a USB peripheral. The USB hub will not appear in any hardware listings on your system, but USB devices do appear when they are connected.

Install the drivers for the USB peripheral.

Install the latest drivers for the USB controller and motherboard chipset.

Note: No drivers or software are required for the USB hub to work with your operating system. The USB hub works independently of software and works with any operating system.

When testing your USB peripherals, make sure that you do the following:

If required, attach external power.

Confirm that the peripheral works on a standard USB port.

If the USB peripheral(s) can be detected on a standard USB port and not on the hub, do the following:

Use a new USB A-to-B cable.

Test your setup using basic USB peripherals, such as a keyboard or mouse.
